The stuff of daily existence is made of atoms, and all those atoms are made of the same three things: electrons, protons and neutrons. Protons and neutrons are very similar particles in most respects.

The atomic nucleus is a busy place. Its constituent protons and neutrons occasionally collide, and briefly fly apart with high momentum before snapping back together like the two ends of a stretched ...

Atoms are the fundamental components of matter, made up of three subatomic particles: protons, neutrons, and electrons. The structure of atoms determines the properties and behavior of different ...

Physicists have found a new “island of inversion” in the nucleus of molybdenum-84, a perfectly balanced atom with equal ...

IN the theory of decay as proposed by Fermi 1, one assumes the existence of elementary processes in which a neutron is transformed into a proton by simultaneous creation of an electron and a neutrino.

Mrs Roberts: What do you think you're made of? Mr Spellman: Big question. Grit, determination, hard-working, handsome, charming, funny. Mrs Roberts: Well, I guess. But you're actually made of atoms.

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

A new study identifies a transition in the strong nuclear force that illuminates the structure of a neutron star's core. Most ordinary matter is held together by an invisible subatomic glue known as ...

Despite decades of taking measurements, scientists cannot agree on how long neutrons live. Neutrons are stable inside atoms, but on their own they decay in about 15 minutes, more or less, into a few ...

Physicists at MIT have for the first time calculated the pressure distribution inside a proton. One incredible finding by the researchers is that the core of a proton generates pressures greater than ...
